Modified "cup-patch" ileocystoplasty for urinary bladder reconstruction in a dog

Full-thickness wall necrosis involving 90 to 95% of the urinary bladder was diagnosed in a 6-month-old Golden Retriever 2 days after ovariohysterectomy. An isolated, vascularized segment of ileum denuded of mucosa was used to reconstruct the urinary bladder. Serial excretory urography over 1 year indicated gradual enlargement of the bladder, with development of a smooth mucosal surface. At 6 months after reconstructive surgery, the dog was voiding urine 2 to 3 times/d and was continent. Results of renal function testing, urinalysis, and bacteriologic culture of urine were all considered normal on follow-up examinations. The cause of bladder wall necrosis was never determined. Ileocystoplasty as described herein appears to be an effective urinary bladder reconstructive procedure in dogs whenever the bladder neck, proximal portion of the urethra, and their neurovascular supply can be spared.
